NOTRE DAME, Ind. — Notre Dame knows it needs a worthwhile passing game. The debacle at Miami made it clear some semblance of an aerial threat must be feared by the opposing defense. Thus, the Irish set to working on that deficiency in a 24-17 victory over Navy on Saturday.

At halftime, those efforts struck a pessimist as dismal. A cynic found them necessary, and an optimist might have even considered them as having taken a step in the right direction.

Junior quarterback Brandon Wimbush reached halftime 4-of-10 for 72 yards. On one hand, he had completed only 40 percent of his passes. By no metric is that good enough. That was the pessimist’s supporting fact.

The cynic looked back a week, remembering when the Hurricanes focused entirely on the Irish rushing game and Wimbush still completed only 10 of 21 passes. The cynic then reaches for a thesaurus and finds synonyms for necessary. Required. Imperative. Vital.

The optimist realized 10 pass attempts gaining 72 yards is an average of 7.2 yards per attempt. That would outdo all but two of Wimbush’s games this season, his 8.65 yards per attempt at Michigan State and his 9.33 yards per attempt against Wake Forest just two weeks ago. Settling anywhere north of seven would be a great step forward for this passing attack.

By the end of the game, the pessimist, cynic and optimist all had to see the same thing: When effective, Wimbush is a bona fide quarterback. Yes, at some point in the future, that initial distinction needs to no longer be part of the equation, but this still qualifies as progress. Yes, that initial distinction is a heftily-meaningful alteration to any phrase, but this establishing itself as fact still marks progress. Wimbush started poorly, but he kept his concentration and finished impressively.

“I thought he settled down into the game,” Notre Dame head coach Brian Kelly said. “What we’re looking for is a guy that will take what’s happened early and kind of reset a little bit, which he did, and refocus. He came back and made some really big plays for us.”

Wimbush completed five of eight second-half passes for 80 yards and two touchdowns, leaning heavily on sophomore receiver Kevin Stepherson.

“I think I just started seeing things a little bit more clearly and adjusted to the tempo that Navy was playing at and went from there,” Wimbush said.

Notre Dame relies on its rushing game. There is no doubt the ground attack is the stirrer in this Irish coffee. (Consider that a wit’s attempt at saying, the straw that stirs the drink.) Wimbush throwing 18 times against Navy — not to count the couple other times he dropped back with intentions to pass but pulled the ball down — is not Kelly and offensive coordinator Chip Long reverting to Kelly’s form of the past, the form of the pass.

Instead, it is the Irish desperately trying to find Wimbush rhythm, if not confidence, in the passing game. As competitive as Navy kept Saturday, this was a week the inefficiency of the educational effort could be afforded.

Notre Dame can, in fact, win a one-possession game.

The last time the Irish did so was against Miami, Oct. 29, 2016. Prior to that, the most-recent close Notre Dame victory came at Boston College, Nov. 21, 2015. Including the victory over the Hurricanes, the Irish had gone 1-9 in the interim.

“For us, it was just a gritty victory,” senior linebacker and captain Greer Martini said. “… I think that’s the next stepping stone for us on to Stanford.”

The nature of Navy’s game plan keeps games close no matter a talent disparity. Finding its way to a tight victory bodes well for Notre Dame, no matter the opponent. In many respects, this remained a mental hurdle needing clearing.

Greer Martini will (not) miss playing against the option.

And he might be the only Irish defender in history to feel that way. In 48 career games to date, the senior captain and linebacker has made 184 tackles, including 15 on Saturday. In six career games against option-specific options, Martini has made 61 tackles. In some respects, Martini made his career excelling against the triple-option, an approach most defenders avoid like a plague.

“It’s just the idea that it’s a lot of run, run downhill, run around,” Martini said. “Just play with a lot of enthusiasm, run sideline-to-sideline.”

Midshipmen head coach Ken Niumatalolo has gotten fed up with Martini, apparently confirming with both Kelly and Martini that he had seen his last of the linebacker. Both assured him he had.

“[Niumatalolo has] tried to block him, he can’t block him,” Kelly said. “… [Martini] just has a really good nose for the football, good sense. What you saw today was the physicality and bending back on the fullback. He was physical, played with the top of his pads.

“It was a clinic in terms of the way he played the linebacker position today.”

Martini insists he will not miss seeing the option, but it cannot be denied the effect the opposing attack had on Martini’s career. As a freshman, he made 26 total tackles. Nine came against Navy.

Notre Dame will host the NHL Winter Classic in 2019.

Yet, the Irish will hope to not be in attendance.

NBC and the NHL announced during the game the 2019 Winter Classic will be held at Notre Dame Stadium on Jan. 1, 2019, between the Chicago Blackhawks and the Boston Burins.

“We are very excited to welcome the Chicago Blackhawks, Boston Bruins and NHL to Notre Dame Stadium for the 2019 Winter Classic,” Director of Athletics Jack Swarbrick said. “I believe it’s only fitting that two of the NHL’s legendary Original Six teams will take the ice for the first hockey game in one of America’s most iconic athletic facilities. Hosting two franchises with so many connections to Notre Dame also provides a unique opportunity to celebrate our hockey legacy.”

On New Year’s Day, a Tuesday next year, the Notre Dame football team will hope to be involved in a major bowl game. Given recent history, it will prefer the Cotton Bowl in Dallas rather than the Orange Bowl in Hard Rock Stadium in Miami.

Mike McGlinchey may be a behemoth of a man with shocking agility for his size, but in at least one respect, he is just like the rest of us.

Wouldn’t you struggle to keep your emotions in check taking the field to the “Rudy” soundtrack in your last home game after a five-year career at Notre Dame? Okay, insist you wouldn’t. What if your mom was waiting for you on the field?

This is not to diminish the losses of receiver Miles Boykin and consensus first-team All-American cornerback Julian Love. Notre Dame will miss both of them, Love in particular. But looking at the Irish depth chart, there are avenues to survival without both.

Notre Dame will return two starting receivers in rising senior Chase Claypool and fifth-year-to-be Chris Finke (speaking of which, see below). A number of options exist to replace Love, though obviously none will match his shutdown abilities. Either rising sophomore TaRiq Bracy will put on the necessary muscle to compete with receivers at this level or rising senior Donte Vaughn will return reinvigorated with health after recent surgery to repair a torn labrum surgery or rising sophomore Houston Griffith will move from safety to get his talent on the field or fifth-year Shaun Crawford will recover from an ACL tear quicker than expected or … or … or … If one of those pans out, the Irish defense should be comfortable in its coverage, buoyed by the stalwart safety combination of Alohi Gilman and Jalen Elliott. (Imagine sincerely saying “stalwart safety combination” just six months ago.)

Look again at the depth chart, and such luxuries do not exist at defensive end. If rising seniors Khalid Kareem and Julian Okwara had not opted to return, Notre Dame’s 2019 dreams would have hit a lowered ceiling nine months before the season began. By no means were they certain high-round draft picks, but the allure of athletic and talented defensive ends may have easily led to some outsized draft hopes.

Their backups are certainly more than capable — rising seniors Daelin Hayes and Ade Ogundeji — but a talented second-unit is as important at defensive end as dangerous starters are. To replace the latter with the former is to diminish the entire enterprise outright.

The Irish could not have recovered from losing both Kareem and Okwara, at least not to the extent where Playoff talk would be viable again. Lose one and it would have still been dubious, at best.

Take a look at the teams expected to be in the mix for the Playoff. Using current championship odds … Clemson at 2-to-1, Alabama at just less than 3-to-1, Georgia at 6-to-1, Ohio State at 8-to-1, Michigan at 16-to-1 and then Oklahoma also at 16-to-1. Those first five have been known for their defenses more than anything else in recent years. Bookmakers put some faith in their ability to reload on the fly.

Notre Dame has not earned that trust, and its roster does not indicate it should have. As well as Justin Ademilola performed as a freshman in four games, inserting him into a pivotal role in 2019 would likely be a recipe for a mediocre season. He is another year of development away from being ready for that role, barring a Matt Balis-induced excellent offseason.

The Irish will need Kareem and Okwara to survive the losses of defensive tackles Jerry Tillery and Jonathan Bonner, but if they play as they did in 2018, that is a reasonable ask. If they continue to develop, it becomes a probability more than a Notre Dame leap of faith.

The Irish will miss Boykin’s back-shoulder reliability and everything about Love, but Brian Kelly and his coaching staff coaxed back the two most-pivotal pieces from NFL draft consideration.

Speaking of Finke, he confirmed his intent to return for his final year of eligibility Thursday evening. And he did it in a way only befitting a man comfortable in his own skin.

With the Wednesday announcement of current junior linebacker D.J. Morgan’s intention to transfer this summer as a graduate with two years of eligibility remaining, Notre Dame’s roster drops to 87 scholarship players expected this coming fall. Included among them, at least 12, possibly 14 linebackers. Before explaining that …

Morgan finishes his Irish career with two tackles in two 2017 appearances as a safety. He moved to linebacker during 2018’s spring practices, but never came particularly close to playing time. It remained difficult to see him cracking into the rotation moving forward given the quality of recruiting classes at the position in the last two cycles.

“I would like to thank the University of Notre Dame for everything they have done for me,” Morgan wrote on Twitter. “When I decided to come here, my main goal was to get my degree from this prestigious University, and I am proud to see that I will be completing that goal this summer!

“During this time I will be searching for a new school to attend as a graduate transfer to finish off my last 2 years of eligibility.”

Before facing Louisville on Labor Day, the Irish will need to be down to 85 scholarship players. At 87 now, that does not include incoming freshman J.D. Bertrand, who had a recruitment handled in a deliberate fashion so as to make him eligible for an academic scholarship. Notre Dame also continues to chase two defenders — consensus four-star linebacker Asa Turner and consensus four-star defensive end Isaiah Foskey — who could balloon the roster count further.

Lacey will need to be ready for at least four games next season, especially with three of these six returning from injury: Tagovailoa-Amosa with a broken foot, though he did at least take some snaps against Clemson; Franklin from a torn quad that will limit him through the spring; and Spears from a torn ACL that could conceivably cost him 2019.

Former Notre Dame quarterback Brandon Wimbush will continue his career at Central Florida. Wimbush announced his graduate transfer destination Tuesday morning.

“The journey continues on …,” Wimbush wrote on Instagram. “A sincere thank you to Notre Dame for giving me endless opportunities on and off the field. Words truly can not (sic) describe what this incredible University and the PEOPLE mean to me and always will mean to me. I’m truly thankful. Cannot say it enough.

“With that being said, I am excited to announce that UCF has granted me an awesome opportunity to play my last year of collegiate football for their great University.”

Wimbush will enter into a starting opportunity, although an unfortunate one and a competitive one. The late November horrendous knee injury to three-year starter McKenzie Milton will almost-assuredly sideline him through the 2019 season. If not for the injury, Milton would either be starting 2019 for the Knights or headed to the NFL.

In his first year of any action, sophomore Darriel Mack played in 10 games for Central Florida, completing 51 of his 100 pass attempts for 619 yards and three touchdowns, including going 35-of-71 for 526 yards and three scores in the two-plus games Milton missed.

Wimbush finishes his Irish career with a 13-3 record as a starter, including four wins during 2018’s unbeaten regular season. After the Notre Dame offense failed to break 24 points in the first three games of the season, offensive coordinator Chip Long turned to Ian Book for a spark, one Book provided and then some.

Wimbush’s role became non-existent after that, aside from a Senior Day start in place of an injured Book, throwing for 130 yards and three touchdowns while rushing for 68 yards.

Mustipher and Co. will now have reason to keep an eye on the Knights in 2019. After going 25-1 in the last two seasons, Central Florida will want to keep the momentum rolling, particularly with Stanford arriving in Orlando on Sept. 14, a week before the Knights head to Pittsburgh. The Knights genuinely entering the College Football Playoff conversation remains unlikely, but topping those two before rolling through the American Athletic Conference would at least start the discussion, especially if a former Irish quarterback headlines the way.

Named 2018’s Next Man In, Wimbush finishes his Irish career with 2,606 yards on 193-of-382 passing with 20 touchdowns and 12 interceptions along with 1,155 rushing yards and 16 additional touchdowns.

AS FOR NOTRE DAME’S QB IN 2019 …Early Heisman odds came from an online sportsbook Tuesday, betonline.ag. Irish rising senior Ian Book was given 16-to-1 odds, tied for ninth on the listing. Given the names ahead of him, Book’s realistic chances of winning the Heisman Trophy are slim. Only Clemson quarterback Trevor Lawrence and Alabama quarterback Tua Tagovailoa have odds lower than 12-to-1, at 7-to-2 and 4-to-1, respectively.

Then come two Notre Dame opponents — Georgia running back D’Andre Swift and quarterback Jake Fromm, both at 12-to-1. Michigan quarterback Shea Patterson checks in at 25-to-1, just ahead of Stanford quarterback K.J. Costello at 33-to-1.

If nothing else, Book can count on some early-season hype if the Irish top Swift and Fromm on Sept. 21.

Dabo Swinney paid tribute to the late Tyler Trent in his speech while Clemson visited the White House 🙏

A sign of a strong program is one that loses players to the NFL before they exhaust eligibility. In that vein, Notre Dame lost a consensus first-team All-American cornerback, its leading receiver and a long-time tease of a tight end. The last of those (Alizé Mack) was never expected back for a fifth season; replacing Miles Boykin’s production is certainly within reason; and a consensus first-team All-American should be expected to take the route junior Julian Love has.

Even with that expectation, losing Love — and to a lesser extent, Boykin — alters the natural roster cycle, the inherent design intended during recruiting. Reloading is always the hope, the next intention, but very rarely is the young backup comparable to the near professional, even by the end of the coming season.

Nonetheless, the Irish got off easy this cycle compared to four of their 2019 opponents …

GEORGIA: Junior running back Elijah Holyfield, the Bulldogs’ second-leading rusher, departs after gaining 1,018 rushing yards with seven touchdowns on 6.4 yards per carry this season. Frankly, that is the least of Georgia’s losses. Three of quarterback Jake Fromm’s four favorite targets will leave eligibility on the figurative table:

MICHIGAN: The Wolverines got good news when quarterback Shea Patterson opted to return for 2019, but losing leading-rusher Karan Higdon (1,178 yards, 10 touchdowns, 5.3 average) will be an issue head coach Jim Harbaugh undoubtedly hoped to avoid. Junior tight end Zach Gentry, Patterson’s third-most prolific target with 32 catches for 514 yards and two scores, will also head to the next level.

On the flip side, Harbaugh could have hoped linebacker Devin Bush (team-leading 80 tackles with 9.5 for loss including five sacks), defensive end Rashan Gary (44 tackles with seven for loss including 3.5 sacks) or linebacker David Long (17 tackles with one interception) might return, but no such luck for Michigan.

DUKE: Junior linebacker Joe Giles-Harris paced the Blue Devils with 81 tackles, including seven for loss with one sack, doing so in only nine games. But losing Giles-Harris is hardly the concern for Duke. The decision to turn pro from quarterback Daniel Jones is.

In his third year as a starter, the junior fought through a broken collarbone to still play in 11 games in 2018, completing 60.5 percent of his passes for 2,674 yards and 22 touchdowns with nine interceptions. He added 319 rushing yards and three touchdowns.

Jones’ decision may come as a surprise, but it is one that should work out well for both him and Notre Dame. Some mock drafts project him as a top-10 pick. In a draft light on quarterbacks — partly because Oregon’s Justin Herbert returned for another season, yet already somewhat counteracted by the Monday draft entry from Oklahoma’s Kyler Murray — Jones could end up being the third or fourth passer picked.

BOSTON COLLEGE: The Eagles will say farewell to junior cornerback Hemp Cheevers after he notched seven interceptions this season, returning one for a touchdown, to go along with 39 tackles.

STANFORD: This will seem like the Cardinal lost a lot to the NFL draft, but it could have been worse: As the departures mounted, so did speculation junior quarterback K.J. Costello might follow them. He opted not to.

Stanford will be without running back Bryce Love after his prodigious two seasons as the starter. Consider that a loss akin to the Irish Love, the inevitable price of enjoying the success in the first place.

Junior receiver J.J. Arcega-Whiteside will capitalize on his breakout season of 1,059 yards and 14 touchdowns, depriving Costello of his favorite jump-ball threat.

Junior tight end Kaden Smith will also head to the next level, in large part thanks to his 47 catches for 635 yards and two touchdowns this past season.

Louisville, New Mexico, Virginia, Bowling Green, USC, Virginia Tech and Navy all did not lose anyone early or pseudo-early to the NFL draft.
